    logger: log.loggers.get('logger1'),

Logging

const log = require('log-ew');

// every property of winston is available by default
log.info('version', log.version);

// inspect arguments in more detail, this can be useful for errors
log.inspect.log(level, arguments…);
log.inspect.error(arguments…);
log.inspect.warn(arguments…);
log.inspect.info(arguments…);
log.inspect.verbose(arguments…);
log.inspect.debug(arguments…);
log.inspect.silly(arguments…);

// logging objects
log.inspect.fields({ firstName: 'John', lastName: 'Smith' }, ['firstName']); // info
log.inspect.fields({ firstName: 'John', lastName: 'Smith' }, ['firstName'], 'debug');
log.inspect.fields({ firstName: 'John', lastName: 'Smith' }, ['firstName'], { level: 'debug' });
log.inspect.hash('Hello', { firstName: 'John', lastName: 'Smith' }); // info
log.inspect.hash('Hello', { firstName: 'John', lastName: 'Smith' }, 'debug');
